Hello, I have at the moment a marantz Av amp and stereo amp as per signature. My REL sub is connected line level to my AV amp therefore no crossover filtering and also via hi level to my stereo amp speaker outputs so I can prceisely set the x over points, gain etc. for better audiophile sound. Now upgrading tyo the AV32R-bp192 which obviously has different x overs etc for each type of input (cd, dvd etc.) so should I just connect via low level from the TAG (and perhaps upgrade the cable) and set evrything up in the TAGs menu? Any help? Thanks, Liam.
